According to the device, the problems of low accuracy and tedious procedures of a conventional measuring device are effectively solved, the operation in a measuring process is simplified, and the errors introduced by conventional operation are greatly reduced.
Description
Technical field
The present invention relates generally to the material properties test technical field, relates in particular to a kind of measurement mechanism and measuring method thereof that is used for film object imbibition ability.
Background technology
Along with continuous progress in science and technology, various new materials arise at the historic moment, and also are gradually improved for the understanding of material different aspect characteristic, and this also has higher requirement to measuring technique.
Imbibition ability test at material, conventional method is to be undertaken by the method for soaking, promptly by of poor quality measure of Measuring Object before and after immersion liquid, still such method material Powdered to some, the block shape is more suitable, and error is less.But only there is its error of film-type material of several millimeter even several microns will be a lot of greatly for thickness, because the general density of such material is less than normal, and because thickness is little, immerse in the liquid and take out again after the imbibition, compole is short during liquid storage in conventional air, can't moment accurately obtain the quality after the imbibition, and cause very big measuring error.
With employed diaphragm paper in lithium ion battery manufacturing field is example, the imbibition ability of barrier film is determining the quality of battery, therefore be the key index that the lithium battery starting material are selected always, but its thickness generally has only tens to tens microns, adopts conventional immersion method, and the barrier film after the immersion liquid is in air, the liquid storage poor ability, electrolytic solution evaporates rapidly, becomes dry, and can't accurately measure quality after the immersion liquid, causes the judgement that provides inaccurate.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, a kind of device that can accurately measure film object imbibition ability to be provided.
The present invention is achieved by the following technical solutions:
A kind of film object imbibition ability measurement mechanism; include the seal case that top seal is equipped with the suspension type balance; the loading hook of described balance is outstanding to seal box; hang with the loading bucket on the hook; described seal case bottom fits tightly on a liquid storage box; be communicated with by a valve one between casing and the liquid storage box; the seal case middle and lower part is surrounded by protective device together with the liquid storage box periphery; described protective device is made by insulation material; described seal box one side is provided with through hole; through hole is connected with pipeline; the pipeline other end is connected with vacuum pump; the pipeline middle part is equipped with valve two, and described seal box one side is equipped with valve three, and the atomizing ejecting device can be installed near seal case one side by described valve three places.
Based on a kind of film object imbibition ability measurement mechanism, its measuring method specifically may further comprise the steps:
(1) testing liquid is packed into liquid storage box and sealing, the switch leveling and the zero clearing of opening balance, film object to be measured sampling places the loading bucket or hangs on the balance hook, and seal case is closed and sealed;
(2) close between casing and the liquid storage box and seal box on valve one, three, open the pipeline valve two that connects vacuum pump, open vacuum pump, (according to the decision of the saturated vapour pressure under the testing liquid normal temperature) closes vacuum pump and the pipeline valve two that is connected vacuum pump when treating that the registration of vacuum meter reaches certain value on the vacuum pump;
(3) the numerical value m1 that treats the stable back of registration record this moment of balance is a quality before the imbibition;
(4) open valve one between casing and the liquid storage box, testing liquid enters seal case with Sprayable, and be adsorbed on gradually on the film object to be measured, the stable back of the registration record numerical value m2 that treats balance is a quality after the imbibition, in this step, peripheral protective device can play insulation effect and collect because the vaporizing liquid seal case that causes of heat absorption and the water of the outside water vapor liquefaction of liquid storage box formation rapidly in the liquid storage box;
(5) after empty pump tail end connects tail gas collecting device, close valve one between casing and the liquid storage box, open the pipeline valve two and the vacuum pump that connect vacuum pump, the liquid gas in the density casing can be discharged, and then open that valve three charges into air on the seal box, finish test operating procedure;
(6) calculate the pick up of thin film fluid according to measurement data m1 and m2.
This device is the device that utilizes vaporizing liquid absorption principle Measuring Object imbibition ability, reduces the seal internal pressure earlier and makes vaporizing liquid, and gasifying liquid is attracted on the film object to be measured, at last by adsorbing the imbibition ability of front and back object mass change Measuring Object;
Described balance can be suspension type, or pellet type and suspension type are dual-purpose;
Described vacuum pump tail end can be installed tail gas collecting device;
Advantage of the present invention is:
The present invention is simple in structure, easy to use, it changes traditional object immersion liquid and is placed in the conventional gas, but the object immersion liquid is placed in the saturated vapour that is adsorbed liquid, prolong the film object imbibition liquid storage time afterwards, and then measure the quality after its imbibition, it is not high to use this device to efficiently solve routine measurement device degree of accuracy, the problem that operation is loaded down with trivial details has been simplified the operation of measuring process, has significantly reduced the error that routine operation is introduced.
